Abstract: 666,235. Conveyer for tiles. CARTERWILKINSON, Ltd. June 2, 1949. Oct. 27, 1948] No. 27947/48. Class 78 (i). [Also in Group V] Feed mechanism adapted to feed pallets and like articles in a continuous row along a guideway comprises (Fig. 5) two reciprocatory feeder devices each having a feeder member (132, 134), which feeder members are situated one behind the other in the direction of movement of the articles, and driving means for operating the feeder device and imparting an operative stroke to each feeder member in turn, while the other feeder member is making an idle or return stroke, so that when the feed movement of one article engaged by the front feeder member terminates, the feed movement of a following article engaged by the rear feeder member commences, a conveyor means supplying the pallets by causing the pallets to follow up the operative stroke of each feeder member, whereby the articles are given a continuous movement along the guideway. General. (Figs. 1a and 1b). Pallets having tiles fixed thereto are conveyed by dogs 39 on endless conveyer 22 along guides 20 towards the left and are impacted by impactor 28 so that the tiles are loosened from the pallets. The pallets pass then on to twin endless conveyer bands 24 where the tiles are manually removed from the pallets. The empty pallets pass on to twin endless conveyer 26 which travels at a slower speed, and thus crowds together the pallets in the longitudinal direction. The pallets now abuting each other, come under the feeding device 30 and are thereby impelled continuously under hopper 32, which feeds on to the pallets a ribbon of formed plastic material. The latter carried by the travelling pallets passes under cutters 34 which cut the ribbon along the edges of the pallets and the pallets each carrying a plastic tile now pass under surfacing device 36 which gives them a surface of cement, and then pass under device 38, which drops sand on to the surface and then pass on to discharge conveyer 360. Depalleting impacting device 28 (Figs. 3 and 4). As the pallet having the tile fixed to it passes along endless conveyer 20 on side pieces 20 it is impacted by impactor 28 which consists of two flat discs 226, 224, which carry impacting discs 230, the flat discs being supported on shaft 228 journalled on adjustable bracket 238 carried by rods 242 so that the impacting discs strike against member 43 which is fixed to slidable member 47 and, on which the pallet rests as it advances so that the tile is shaken from its supporting pallet. Feed mechanism 30 (Figs. 5 and 8). The feed mechanism comprises two similar reciprocating pawls 134, 132 driven through gearing from motor 144. This pawl 134 (e.g.) is supported on slider 126 which slides along a pair of longitudinal bars 128, the slider being pivoted to link 138 pivoted to arm 114, which is pivoted at 118 to the frame. Arm 114 comprises sliding member 122 which is driven by a crank pin 104 fixed on rotatable disc crank 100 so that the pawl reciprocates. The two pawls are so arranged that as one retracts the other advances so that there is a continuous urge given to the continuous stream of pallets, the retracting movement being quicker than the advancing movement. Cutting device 34 (Figs. 9, 10). Cutting device 34 is driven from rocking arm 314 pivoted at 318 and rocked by rod 208 operated from the feeding devices, the movement being transmitted, through lever 293, to carriage 290 which is thus reciprocated along rails 292. The carriage has pillars 301 on which run sleeves 307 which carry a frame carrying cutter 309 and punch 312 and also supports shaft 302 on which is pivoted arm 304 integral with arm 303. As the carriage is reciprocated, fixed roller 296 strikes arm 303 on the carriage on the backward movement, and thus depresses arm 304 which latter presses down pads 306 fixed to sleeves 307 of the said frame and causes the cutter and punch to cut and penetrate the tile. Pads 306 are resiliently supported by the springs shown. Surfacing device 36 (Fig. 9). Sieve 323 is shaken by lever 330 driven from lever 314 so that the cement is shaken on to each tile. Hopper 32 (Fig. 12). This has a roller 262 which rolls out the strip of formed plastic material on to the pallets beneath. Sanding device 38 (Fig. 1b). The sanding device like the surfacing device, has a sieve which is reciprocated by lever mechanism 340, 336, 314 so that sand is shaken on to the tile. Specification 464,213, [Group II], is referred to.
